T o all zlhom z't may concern:

Be it known that I, PATRICK CALLAHAN,

a citizen of the United States, and resident of Stratford, in the county of Fairfield and State of Connectlcut, have lnventcd certain new and useful Improvements 1n Maclnncs for Blowing Powdered Poison on Plants, of'

which the following is a specification.

This invention relates to new and useful improvements in devices for blowing dry powdered Paris green or similar dry poisons upon growing vines 4or bushes, and is especially adapted for use upon potato vines when grown in rows in the usual way.

The object of the invention is to provide a horse, drawn machine which is adapted to dust dry poison upon four rows of vines simultaneously and with the traveling of the machine once through the rows; to provide a machine which is simple in construction,

scribed, illustrated in'the accompanying form of ina-chine.

drawings, and pointed out in the claim hereto apended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of theclaim may be resorted to without departure from the spirit or sacrificing any of the advantages ol. the invention. r

Similar characters of reference denote like or corresponding parts throughout the sev-` eral figures of the accompanying drawings forming a part of this speciticatiomaml upon which y vFigure 1 shows a plan view of my novel Figo@ is an enlarged detail sectional elevation taken on line l of Fig. 1 and Fig. 3 is an enlarged vertical seotional elevation taken on line 3 of Fig. 1 showing the powder' receptacle, agitator,

feeding device andrblower for distributing.

the powder upon the plants.

As will be noted the machine is in the form of a two wheel vehicle which is adapted to be drawn by a single horse that l,travels between the two center rows and further lncludes four dusting devices properly spaced one from the other to dust four rows of vines at the same time. The machine thus treats two rows of plants on each side of the,

furrow through which the horse travels, the powder being .preferably fed `out and .blown forward and downward in line with the travel of the vehicle. The several dust feedmg devices are connected and driven from the main driving shaft upon which the supporting wheels are`mounted. y i

Referring in detail to the characters of reference marked upon the drawings 5 represents the supporting wheels, 6 the axle upon which one of the Wheels is. secured and upon whlch the other 1s free to turn.

-7 representsfthe frame the longitudinal members of which are provided with bearings to accommodate the axle 6. It will thus be seen that the weight'of the machine and the frame as a whole isabout equally divided forward and aft` of the axle so as to insure its hanging lightly `upon the horse.-

A sprocket w veel 8 is loosely mounted upon the shaft 6 and is provided with a clutched face hub that is adapted to be engaged by a slidable clutch member' 9 which is normally held in engagement with the clutch of the sprocket by means of a spring 10. This slidable clutch member can be thrown out of engagement against the action of the spring at any time through the medium of a lever 11 that engages the' slidable clutch member and is pivotally connected to a cross member of the frame as at 12. The axle is provided with several pin holes'l-S which makes it possible to set the wheels out farther in order to better accommodate a field of potatoes where the rows are arranged farther' apart.

14 represents a longitudinal feed shaftA which issupported in bearings 15 secured to the frame and as will be noted (see Fig. 3) extends throughthe fan casings. This feed shaft is driven from the sprocket wheel 8 through a sprocket chain 1G that engages ay suitable sprocket wheel 17 upon the feed les shaft 'l-i. A gear 18 is also mounted upon this shaft and serves to drive a pinion A19 i mounted upon a short shaft 20 journaled in bearings vof the brackets 21 secured to the members 7 of the frame. This idler in turn'operates a pinion 23 secured to the fan shaft 24 which like the feed shaft 14 is dispese eresswse of the njmchne eed eli tends fshrough the fen seeing; .in pdg,

the fans 26 are arranged upm; in e wey te be turned therewith. This liv of gear connections obvousy Serves -f the fan ehat at e very much highel reise Speed than lhe .feed shaft is course, esimbe.
